FURNITURE FOR FORMING PAPER-BOX BLANKS.:

SPECIFICATION forming part of Letters Patent No. 705,389, dated July 22,1902.

Application filed January 17, 1902. Serial No. 90,143. (No model.) v

To @ZZ whom it may concern: `v

Be it known that We, JOSEPH TAYLOR GRAW, a` resident of Jersey City, inthe vcounty ofHudson and State of New Jersey,

full, clear, and exact description.

The purposeof our invention is to provide furniture for formingpaper-box blanks and the like, which furniture'inay beset up with'- outthe use of corner pieces and may be quickly assembled and placed in anydesired position, two pieces wherever brought in contact at right anglesto each other forming a welldefined sharp corner with or without rule orknife applied.

Another purpose of the invention is to construct the furniture of woodor metal and so apply a score or knife blade or rule thereto as torender the two 'parts virtually one and cause one to strengthen theother.

A further purpose of the invention is to provide novel and effectivemeans for automatically forcing a blank whenV made and scored fromengagement with the knivesor score-blades. ,I

The invention consists kin the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of our improved furniture for cutting andscoringblanks for boxes, the furniture being shown set up in a form.Fig. 2 is a vertical se'ctionltaken on the line-22 of Fig. 1. Fig. 3 isa perspective view of a piece of the improvedffurniture constructed ofmetal. Fig. 4 is a transverse section throughthe same, illustrating oneof the automatic releasing devices in elevation. Fig. 5 is a perspectiveview'of a piece of furniture constructed of wood and differing 5oslightly in construction from that shown in Fig. 3, and Fig. '6 is atransverse section through the furniture shown in Fig. 5 and a sectionthrough one of the automatic releasing devices carried thereby. Fig. 7is a perspective view of the piece of furniture and score-blade appliedthereto. Fig.8 is a transverse section through the furnitureshoWnin Fig.7. Fig. 9 is a perspective view of a plain piece of furniture andattached score-blade, and'Fig. 10 is a plan'view of several pieces offurniture in position'to form a squareand illustrating a slight changein construction; and Fig. l1 is a perspective view of a portion of"'apiece of furniture, showing a blade or rule adjustably applied thereto.Y

A represents a piece of the improve'dfurniture, which is made of Wood orof metal and is rectangular in cross-section. The furniture may beofnany desired length, and in the preferred form each piece isstraightat one end, but is provided with an angular recess 10 at itsopposite end,`and each of saidl pieces is also provided with Vseries ofapertures 11, which extend through ,from the upper to the lower face.The wall Of the apertures is without a lining when it is AconstructedofV metal, as shown in Figs. 3 and 4; but when the furniture is made ofwood a tube 14 is closely ,made of cork, and eachcomprises a tapering head-fmember 12 and a shank member 13, adapted to iit snugly in anaperture 1l or in the releasing devices areof 'such' length that whenthe releasing devicesare subject-ed to pressure in cutting and scoring ablank laid upon a set-up form said Shanks will extend to the under sideof the furniture and engage bushing 14.. Preferably the slianks 13 of 95IOO with a face of the press employed. The heads and Shanks of thereleasing devices are preferably semicircular in cross-section, so thatwhen the devices are forced down the shanks will curl to an extent andbind themselves in the apertures.

A score rule or knife C maybe simply laid against the longer side of thefurniture, extending a suitable distance beyond its upper face, or therule or knife may be and usually is attached to the furniture by meansof screws 15 or equivalent fastening devices, as shown in Fig. 8. Whenthe rule or knife is thus secured to the furniture, it becomes anintegral part of it and prevents the furniture from warping. Vhen therule or knife is applied to the furniture, one end is flush with thestraight end of the furniture, while the opposite end extends beyond therecessed end of the furniture, as is shown in Fig. 7.

In Fig. 9 we have illustrated the furniture as straight at both ends andthe rule or knife as extending beyond one end. Under suchy constructionan interlocking form of corner is also obtained; but preferably one endof the furniture is recessed, as is shown in Figs. 3, 5, and 7.

In making up a single square form two long pieces of furniture with ruleor knife applied and two shorter pieces are selected. Correspondingpieces are placed opposite each other, and in opposing pieces thestraight end of one is made to enter the recess in the other, the endportions of the rules or knives being thus brought together, formingsharp welldefined angular interlocking corners.

NVhen the pieces of furniture are plain or square at each end, as shownin Figs. 9 and l0, in making up a form the end of one piece is made toabut against the extended portion ofthe rule or knife of the opposingpiece. When the form is made up of a multiple of squares D, as shown inFig. l, wherever two end or side pieces of furniture-come togetherthroughout their length the rule or knife is omitted from one of them,as is illustrated at d in said Fig. 1.

After the furniture is set up to produce the desired shape of blank theform thus obtained is keyed or otherwise locked in a frame E by Wedges16 and blocks 17 or like devices. The form is placed in a press, and thesheet from which the blank is to be produced is laid upon the upper faceof the form and shaped. As soon as the blank is relieved from pressurethe releasing devices, which are under compression at that time, expandand force and hold the blank from engagement with the score rules orknives.

It is obvious that with furniture constructed as described a form can beexpeditiously and conveniently set up, as pieces of the required lengthcan be quickly selected and set in position and the furniture can berepeatedly used and stored, so as to be convenient of access. Itis alsoevident that theimproved furniture is interchangeable, as it may beturned end for end and otherwise shifted as may be required in making upaforln of given shape.

In Fig. l1 we have illustrated a piece of furniture A, to which theblade or rule is attached in an adjustable man ner, so that as the knifeor rule becomes worn it may be set up quickly and conveniently. To thisend the blade or rule is provided with vertical elongated slots c and isfastened to the piece of furniture A by screws c passed through theslots.

Having thus described our invention, we claim as new and desire tosecure by Letters Patentl. In furniture for formingblanks for paperboxes and the like, a form, comprising four rectangular wooden pieces,each apertured and having one end straight and its other end recessed onits inner face, metal bushings in the apertures of the pieces, corkreleasing devices having tapering heads and fitting in the apertures ofthe pieces, and a score rule or knife secured to the outer face of eachpiece with one end flush with the straight end of the piece, and itsother end projecting beyond the recessed end of said piece, the piecesbeing arranged with the straight end of one piece entering the recess ofthe adjacent piece, whereby the pieces are prevented from splitting orwarping and the rules or knives will be brought ltogether at the cornersforming well-defined angular interlocking corners, as set forth.
